CLEANING-TOOL.

Patented Mar. 26, 1912.

Application filed Jannary 27, 1908. Serial No. 412,710.

To all whom it may concern Be it known that I, IRA H. SPENCER, a'citizen of the United States, and a resident of Hartford, in the countyof Hartford and State of Connecticut, have invented a new and ImprovedCleaning-Tool, of which the following is a specification.

My invention relates to the class of cleaning tools more especiallyadapted for use in connection with pneumatic cleaning, and the object ofmy invention is to provide a tool of this class having numerous novelfeatures of advantage and utility. A form of tool in the use of whichthis object may be attained is illustrated in the accompanying drawings,in which-- Figure 1 is a view in side elevation of a tool embodyin myinvention. Fig. 2 is a bottom view 0 the same. Fig. 3 is a view in1central transverse section through the too In the use of pneumatic.cleaning tools prior to my invention it has been found difficult tothoroughly remove the dust and dirt from certain structures aslinoleum,-oilcl'oth and the like such surfaces after having been cleanedhaving adusty appearance. I have found by experiment that by using acomparatively smooth fibered mouth-piece this dirt and dust may 'bethoroughly removed so that such surfaces as linoleum, oilcloth and thelike after having been cleaned will be free from this dusty a pearance.It is desirable that such a tool may also be constructed to be used inconnection with a brush in which case the flexible fiber mouthpieceshould project to a point near the outer end of the bristles. It istherefore important that the parts znall be so constructed and arrangedthat the suction through the tool will not cause the comparatively thin,flexible mouth-piece to collapse and be drawn inward, thus obstructingthe intake opening.

I have provided a tool in which the flexible fibrous mouth-piece ismaintained in approximately its normal form, such a str uc-' ture beingillustrated in the accompanying drawings, in which the numeral 6 denotesthe head of the tool having a neck 7 to which a nipple, hose or likepart may be connected. This neck has an opening 8 leading into a chamber9 in the head. A shoulder 10 is formed extending about the lower portionof the head and in this shouldered part a recess 11 is formed. A base 12of any suitable material is secured within this recess, and extendinginto this base are the bristles 13 of abrush which are secured in anyordinary manner. A buffer 14 extends about theouter surface of theflange 15 which partially forms the recess.

Within the recess 11 is located a support 16. A mouth 17 opens from thechamber 9, this mouth forming an intake opening for the flow of air intothe tool and through the structure. The support 16 extends completelyabout the mouth-17 and is extended to a point to thoroughly support amouthpiece lS. This mouth-piece is formed of leather or other suitablefiber, the edge of the mouth-piece being located approximately in theplane of the brushing surface of the bristles of the brush. Thismouthpiece should extcnd some distance beyond the support forming themouth proper in order that it may work effectually for the purposeintended, and the support 16 is projected within this mouth-piece to adistance to sufliciently support the mouth-piece from collapse under thepressure exerted by the air..used for cleaning purposes.

The mouth-piece 18 is constructed of leather or other similar suitablematerial in order that a surface may be thoroughly cleaned by therubbing contact. In order to produce the best results thismouth-piece ismade comparatively flexible. The intake opening or mouth, in order todispose of the water, dirt, etc., is of comparatively large area andthere is, therefore, a tendency to collapse the mouth-piece and cause itto obstruct the opening into the tool. The support 16 is thereforeextended downward to a point somewhat close to the edge of themouth-piece, in order to prevent such collapse, so that satisfactoryresults shall be produced in the cleaning operation.

While the support 16 is shown and described asbeing continuous andextending completely around the mouth, it is not-,essential to theinvention that it shall be so formed.

The brush may be easily removed for the purpose of interchange orrenewal and the mouth-piece may also be easily and quickly removed forlike purpose, the construction of the parts including the leathermouthpiece providing means for frictionally holding both the brush andsaid mouth-piece in place.

I claim' 7 1. A head having a chamber and-a projection extending fromthe side of the head and having an opening into said chamber, a flangesurrounding the lower side of the head, a support projecting from withinsaid flange, and a mouth-piece secured within said flange and extendingabout said sup port.

2. A head having a chamber with an outlet therefrom and an intakeopening thereto, a shoulder formed upon the head and having a recess, abrush base located within said recess and with bristles extendingtherefrom, a mouth-piece located within an opening in the brush base,and a support for the mouth-piece projecting from the head within saidmouth-piece but terminating short of the edge thereof.

3. A head having a chamber with an outlet therefrom and an intakeopening thereto, a shoulder formed upon the head and. having a recess,-a support integrally formed with said head and project-ing through saidrecess, a mouth-piece surrounding said support and with its edgeprojecting beyond the edge of the support, and a brush base havingbristles and located within said recess.

4. A head having a chamber with an outlet therefrom and an intakeopening, a support extending about said intake opening, a flangeextending about the head at a distan'ce from the support and forming arecess, a mouth-piece of flexible fibrous material located against saidsupport and projecting beyond its edge, and a brush removably securedwithin said recess between the mouth-piece and flange.

having an intake-opening, a brush disposed about said intake opening,and'a wiper band interposed between the brush and the intake opening andlocated adjacent to said opening, substantially as set forth.
